If you want to install or run a different operating system on your computer, such as Windows, Linux or DOS, you may need to create a bootable USB drive with Rufus and ISO files. Rufus is a small application that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. ISO files are image files that contain the data of a CD or DVD, such as the installation files of an operating system.

In this article, we will show you how to use Rufus and ISO files to create a bootable USB drive in a few simple steps.

• A USB flash drive with at least 8 GB of free space.
• An ISO file of the operating system you want to install or run.
• A computer with Windows 7 or later.
• Rufus, which you can download from https://rufus.ie/.

1. Insert your USB flash drive into your computer and run Rufus. You may need to grant administrator privileges to Rufus.
2. Select your USB flash drive from the Device drop-down menu.
3. Under Boot selection, click SELECT and browse to the ISO file you want to use.
4. Under Image option, choose Standard Windows installation if you are using a Windows ISO file, or DD Image if you are using a Linux or DOS ISO file.
5. Under Partition scheme, choose MBR if your computer uses BIOS or UEFI-CSM, or GPT if your computer uses UEFI.
6. Under File system, choose FAT32 if your ISO file is smaller than 4 GB, or NTFS if your ISO file is larger than 4 GB.
7. Under Cluster size, choose the default value.
8. Under Volume label, enter a name for your USB flash drive.
9. Click START to begin the process. Rufus will warn you that all data on your USB flash drive will be erased. Click OK to confirm.
10. Wait for Rufus to finish copying the ISO file to your USB flash drive. This may take several minutes depending on the size of the ISO file and the speed of your USB flash drive.
11. When Rufus is done, you will see READY at the bottom. Click CLOSE to exit Rufus.
12. You can now use your bootable USB drive to install or run the operating system of your choice. To do so, you may need to change the boot order in your computer’s BIOS or UEFI settings to make it boot from the USB flash drive first.
